Ten Years of Sesame Street was an exhibit held at The Smithsonian Institution from June to September 1979. Celebrating the show's tenth anniversary, the exhibit featured a 50-foot replica of a portion of the street set, with mannequins of Bob, Susan, Mr. Hooper, Big Bird and Oscar the Grouch. The exhibit also featured special video highlights from the show's first ten years. Screened throughout the summer were the tenth anniversary special, A Walking Tour of Sesame Street, and Children's Television Workshop: Ten Years of Film, a collection of film compiled by John Hanhardt.
